Hi List, I have a Server where a simple SQL is taking a long time to return the results the Server settings are as follows:
Debian GNU/Linux 7 (wheezy) CPU: Intel(R) Xeon(R) CPU E5405 @ 2.00GHz Mem: 16GB HD: SSG 120 GB Postgresql 9.2 postgresql.conf shared_buffers = 1536MB work_mem = 32MB maintenance_work_mem = 960MB effective_cache_size = 4864MB I did a test with the following SQL: select * from MINHATABELA It took 7 minutes to return the result. I did the same test on a Server: Windows Server 2012 Standard CPU: Intel(R) Xeon(R) CPU E5-2450 @ 2.10GHz Mem: 24GB HD: HD 500 GB Postgresql 9.2 postgresql.conf Default settings that come with the installation The same SQL returned in 3 minutes. The test in both Servers were done bench. This table has 1888240 records whose size is 458 MB I believe that in both Servers the response time of this SQL is very high, but the main thing in LINUX Server has something very wrong, I think it is something in the settings. What can I be checking? -- Atenciosamente Daviramos Roussenq Fortunato
